Review on SadoTech'S Wireless Doorbell Kit: 1000-Ft Range, Waterproof And Loaded With 52 Chimes And LED Lights by Bobby Watkins

It's a set of inexpensive, simple doorbells with a traditional ding-dong and few preset musical chimes, 4-level volume control, 2 buttons. That's exactly what I needed for the garage and back porch. Very easy to use. Pushing the volume button on the chime will cycle through the 4 levels. The highest volume is very loud. The 2 up-down buttons on the chime lets you select the preset chimes. Areas of concerns: The buttons can be too easily taken out of the brackets, with a very light push from the bottom. The buttons have small plastic hooks on the back that latch on to the brackets. These hooks look like they should be stronger for durability. For the price, I'm OK with these small issues, but wish the brackets were better designed.
